So satisfying watching your work. Also appreciate the effort you put into editing and putting it together (music selection also 9/10). Keep up the good work Dave !
Yeah, that is for sure, really boils me when I tell them that we will need a 20 Tonne machine and they get in a 5 tonne machine because the think that it will save money...
Cheers from the USA, Dave. I truly appreciate your talent in drill hole spacing and getting the charge just right, especially when you are doing it upside down!😂
You can tell that the granite is very fractured before you fire the shot, by the way the walls were cracking all around the edges. Great job Dave and pretty to watch. 👍🏻
Excellent job Dave! I bet you saved those excavators many days of digging with your secret bangers! Hopefully the general contractor has seen the light & felt the earth shake for future jobs! Stay safe! Jim
Oh... I see that you have just made an account, congratulations and I'm the first subscriber?? I can always find work for guys with big machines that are not afraid of using the breaker.
As awesome as the Blasting was the guys running the excaators showed some serious skill. I was at a job sit that had 60 ton excavators with hydralic powered rock grinders and they spent weeks trying to do the job. You and these guys seem to make an easy job of it.
Another great video. Thanks, Dave. Have you done a video explaining the steps in loading up a hole like we saw here? I looked though your videos and didn't spot one, but there are very many videos and I may have missed it.
That should knock at least a week off the job I reckon, great placement of the bangers to take the top part off that back wall as well. That view looks really familiar as well Dave, is that the same job/area you were at a while back? Looked like a great day to be on the water with a line over the side.
I've been subscribed to your channel for ages, and just realized today, that because I'm in the States and I am and I have googled a couple questions from watching your videos, I am sure I am now on the FBI watch list!!! LOL Thanks Dave. ;)
I think it was just because if the falling dirt off the sides, but that blast at 7:38 seemed to move the ground a lot more than most....but I think it just looked like that because so much dirt came down the sides
What explosive were you using? It's always a joy watching waves travel through rock. Have you seen the super heated steam drills? They look good for avoiding jams.
Seeing you lean hard on the drill I wonder if you could add a container to the drill that is filled with water by a venturi pump when additional weight is needed. All as a closed system that fills from/empties into a container somewhere on the ground.
The drill that I used here, including the air leg bracket that is fitted to weighs about 25.5 Kg or 56 pounds, another 5 KG would be a big help. There are bolt on weights available in Europe, never seen any here though.
@@demolitiondavedrillandblast Maybe then there is something to this idea. 🙂 A tank with 5L should be possible to attach somewhere where it suits the balance of the drill. Wouldn't even need to be rigid, could probably be a bladder.
Do the contractors know what type of soil / rock they're going to encounter when submitting their bids? How much does blasting increase the construction costs?
Usually there is a soil test done that gives a pretty good indication what is in the ground, In many cases blasting decreases excavation cost because it speeds up the job, as compared to just smashing away with the hydraulic breaker.
@@demolitiondavedrillandblast Always assuming that the soil test results are for the correct block of land. 😮 I worked on a kitchen in a two storey house that had cubes of concrete cut out of the floor so that additional piers could be installed and the outer brickwork properly supported. 😢 The reason for the trouble? The soil testing firm mixed up the results for that particular house with another house several suburbs away. It resulted in the other house having multiple extra footing piers when the stable soil at the site didn't require any. It turned out that the house I was working in had been built on an old filled in gully and was therefore in need of foundation piers to support the weight of the house. A very bad and costly fubar. Fortunately no one was killed or injured. Mark from Melbourne Australia
You are the Master Blaster Dave and the new hammer drills look to be working fine. What a site - already had piles put in down one side which must have been a job. Is that Port Phillip Bay you were gazing down on sir?
You might have answered this question in the past but, do you bid jobs like this? Or do you charge by the hole? Or total meters drilled? Or hour? And always look forward to your videos
That is easy to do with a det cord shot, you just have to make sure that all the connections are done in a manor that makes them bi directional and then include a redundancy loop. With signal tube hook up it is not that simple, all you can really do is run witness tube out from the ends of each row to indicate that every row has propagated all of the way to the end.
Very interesting to watch you do your thing! I'm curious to know if your body reacts to the vibrating tools you use in any way? Handheld tools are almost completely gone from this industry where I live.
Interesting subject, some people seem to develop muscular - skeletal problems quite quickly from using these type of tools and other have little problem. I have been using rock drills 30 years and drilled about ~45,000m and no big issues. One point that somebody suggested to me was that smokers have a lot more problems because of their compromised circulation. I would like to do drill rig only jobs but there is just so many small jobs that need to be done, often where a drill rig will not fit. Where are you located my friend.
@@demolitiondavedrillandblast Thank you for answering that. I was really wondering how that might be. Interesting point about the smoking. That could be a contributing factor. With that much drilling you should have noticed by now! :) I'm located in Norway. Western parts where the fjords are. I live in an island on the coast. We have mostly gneiss, granite and marble (marble is what's mined in this area) Hard stuff, mostly.
You live in a beautiful part of the world Pal, but a bit too cold for me. I have noticed how nearly every drill and blast contractor in Scandinavia seem to have a Tamrock Commando rig for doing the smaller jobs, I would love one of these but they are outrageously expensive here, typically ~ $100,000 or 700,000 kr. and that is for a machine with 5000 hrs.
@@demolitiondavedrillandblastBeautiful but with its drawbacks, just like your area😊 The Sandvik/Tamrock mini machines are really genius! If you could walk there, the Commando can probably get there too. I would guess the economy of one is similar to the economy of an excavator of similar kw. You could probably justify a higher rate towards the customer too. Are you considering getting into one?
Are I considering getting one? ...Yes, it it was good condition and the price was right, I have the drill mast mounted on my 3.5 Tonne excavator but this has a pneumatic drill and external dust collection system - ua-cam.com/video/SIkyt6t8slg/v-deo.html This is good but not perfect.
Dave. On the slo mo of the last blast did i see the shockwave travel out through the rock and return or am I just see the slight offset in detonation timing? Great video!
Another job well done. I can't believe you do that with a sinker. Done a lot like that back in the old days though. What size snausages are those, they look longer then the standard 16?. Presplit powder?
I'm pretty handy with a sinker, can drill 4.5m if I have good ground (4.5 is longest drill rod That I have for them). The sausage is 32mm x 700mm (27.5 inches x 1.25 inches). The long ones are favored for tunneling work, all that I could get at the time.
I think it would be really interesting if you could work with the slo-mo guys on a blast where you don't need to use cover. The really slow shots they get would be fantastic viewing.
@@demolitiondavedrillandblast Yup, there is so much that can be learned from watching a blast or 5 at 200,000 fps they frequently use with their very costly high speed camera. The collab would show the details without the high cost of the camera.
He does have videos taken out in the middle of nowhere where there's no cover. Like digging a trench with about 50 to 70 explosive holes. What happens is a hail storm coming down with chunks of rock, the size of a cantaloupe or a basketball with sharp edges. Very fun to watch!
@@henryD9363 yup, I've watched them, now picture the blast itself at extreme slow motion. the way the charge causes the rock to break, how the rock starts to shift, the details that Dave hasn't managed to catch with his own slow motion clips.
Dave. Are you excavating the underground basement for a car park under apartments, if the white tube. you cut up are explosive whats the stuff you pour over top of it, is the the initial charge that you wire up. Thanks for the Videos and excuse my questions 😊
I think he doesn't often give these details. My guess is that the UA-cam algorithm doesn't want certain words to be spoken that pertain to particular powdered stuff that will very quickly go from a solid material to an extremely high pressure gas, if you know what I mean: Demonetization. But I think he often uses something like an ammonium nitrate/fuel oil mix. Then there's other stuff that causes it to go Boom from the bottom upward.
We go to a lot of trouble to prevent this John, It is not to difficult to calculate the vibration amplitude at the nearest house when you know the maximum instantaneous charge mass, the distance to target and ground "K" factor. There are statutory limits for blast vibration that I must adhere to - and they are quite conservative.
That's interesting I didn't know they blast under dirt like that. I suppose that makes a ton of sense assuming the blast doesn't throw rocks like ball bearings, but considering the blast charge that's a really interesting way to go about this. Makes a lot of sense though. Thanks for showing me the process.
He does have videos filmed out in the middle of nowhere where he doesn't do any covering. Like one trench demolition with about 80 holes and no cover. It looks like a brief hail storm came over with chunks the size of watermelons or cantaloupes or baseballs with very sharp edges. Amazing to watch But this can only be done when there's no structures or people etc around.
It is a good way to blast in urban areas because not only does it do a good job of controlling any flyrock but it does a great job of shutting down the noise - which very quickly brings complaints.
No, provided you have enough total cover, you just have to be very sure that the initial cover does not have any rocks in it that may damage the plastic signal tubes.
Problem with that fissured rock is its hard to drill and it takes a crap load of shock to loosen it as it doesn't build pressure good you get shallow shock spikes . Nice bangs though good job mate
Dave, good morning from the UK. I think that this is the first video that I have seen where you have done a trial for the customer, does this happen often?
Yeah, If the customer is a bit unsure I sometimes say, "lets give it a crack for a day and see how it turns out and see if it is an economical advantage for you" This way the customer does not feel like he has to make a big commitment when unsure. As it turned out on this job I just gave them a bit of a help in between other jobs that I was stuck on for ages. They just pressed on with the breaker when I was gone.
Dave we could’ve used you putting a new fence on a property I worked on , it took 3 weeks to do 1.5 ks with a bloody jackhammer,pick and crowbar then we had to cart soil in to bed the posts and strainers , the owner of the property was trying to save money by us doing it instead of getting a contractor, I went back for a visit a few years ago and his son had pulled the fence down and turned the area into a quarry for the farm , bloody excellent tracks on the farm now better than the highways we use today no potholes but a hell of a lot of traffic just maintained properly
I hear you Roger, I have had a similar experience - I blasted a heap of farm fence post holes, just in mudstone but it was a bit hard to auger. Fence went in and looked good, few weeks later the fence contractor calls up and says we have to do it all again because the customer did not like the fence line interrupting his view to the horizon while he was sitting in his pool. He got in a D9 dozer and ripped thousands of cubic meters out and then we put the fence in again!!
just a few rocks - nope...loads.. .no match for Mr D - watch me turn them into pebbles - thanks for sharing this with us stay safe and well sending regards
Dave by watching your video it did look horrible rock to drill, but what made me laugh was your little dirt dance. Keep it up mate good video thanks 👍👍👍👍😂
Fascinating to watch you in action. You deserve every cent you earn, and more. What I don't understand is how can this be affordable for a domestic project. Surely it increases the cost so much as to make it prohibitive?
I got the feeling those excavator operators needed a little encouragement to do it your way. Dirt not rock cover! Once they saw the results and got into the routine it worked out well.
Now, that's the height of efficiency. A five hole shot yielded at least one pebble that you didn't even drill into. Good going, Dave. Have you used your new toy much?
Hi Hans, good question. I own a truck load of blast mats that I rarely use, reason #1 - I have to take another truck load to and from the job (employ an extra person) when in nearly every case the soil is already there. #2 The soil provides a higher level of protection (provided you put enough on). #3 Blast mats might stop flyrock but they do little to manage the blast noise and it is the noise and over pressure that brings complaints (and unwanted spectators). #4 I no longer have to spend my weekends repairing blast mats. Thanks for watching.
There is actually a break water just down the road made out of my rock from a big housing estate development project 15 years ago. - The Developer managed to sell the whole 3500m3 of busted rock.
With a portable crusher on sit, you wouldn't need ANY fill or concrete aggregate. I used to service the tracked portable machines. Couple hours and that pile would be perfect size.
That sixteen-hole shot looked like you were loading them heavy. That should give the moles and gophers in the vicinity a bit of bother, if you have such creatures down under. I was hoping to see the Lady in Red on the job and watch how fast the drilling went. Maybe next time. Thanks Dave, take care and be safe. Cheers.
I wonder what the cost difference was between having a whole crew with hydraulic breakers vs just having you come in and break it the right way. I'm assuming you saved them several man-hours doing it your more entertaining way...
"Lots of Rocks" is an understatement.... might as well open a granite quarry.
Heck yeah!
There was one around the corner
So satisfying watching your work. Also appreciate the effort you put into editing and putting it together (music selection also 9/10). Keep up the good work Dave !
Glad you enjoyed it John - the music selection is that hardest part.
@@demolitiondavedrillandblast So what was the cost for the site prep? and how much more was that than the orig quote?
Great job as always. What amazes me is how easy it is for the excavator to change implements, and how they don't fall back off....
There is a little sliding jigger in the hitch that locks the bucket on - lot better than the old days of manual bucket changes.
@@demolitiondavedrillandblast thanks for the info
@@demolitiondavedrillandblast Yeah, I remember watching those manual bucket changes when I started my Carpentry Apprenticeship back in 1984. Slow!
As ever, amazing to see such force precisely applied. Stay well, Dave.
I walk a fine line Chris.
I love when the contractor has all the required equipment on site.
Yeah, that is for sure, really boils me when I tell them that we will need a 20 Tonne machine and they get in a 5 tonne machine because the think that it will save money...

You can tell that the granite is very fractured before you fire the shot, by the way the walls were cracking all around the edges. Great job Dave and pretty to watch. 👍🏻
Yeah, terrible stuff to drill. Thanks for watching.

I've worked with these guys before and they are good, I was not real keen on doing too much on this one though.
I believe that explosives were necessary. Those excavators couldn't break through that rock. They tried, and then called Dave
Loved working with you mate.
Cant wait for the next one.
Oh... I see that you have just made an account, congratulations and I'm the first subscriber?? I can always find work for guys with big machines that are not afraid of using the breaker.

@10:46 - Do the danger-sausages have markings for cutting or do you just eyeball based on the hole that you drilled?
I just eyeball it.

Nice bangs Dave :) that rock looks like a nightmare to work with ! Tight site too !
I was not good David.
going that deep must be a full basement going in! how's the new drill working out? meeting your expectations?
It has an underground car park that would make a shopping center blush. New drill is sweet!
@@demolitiondavedrillandblast those car parks are considered part of the basement over here!
Nice one Dave , that second blast loosened up more so they got a bonus
Sure did Chris.

That should knock at least a week off the job I reckon, great placement of the bangers to take the top part off that back wall as well.

Greetings from the Netherlands 🇱🇺😎
Sure is Arie.
What happened to your new drill.
This was before the new drill Tim.
G'day great video mate
Hey, thanks Murphy.
Dave we could’ve used you putting a new fence on a property I worked on , it took 3 weeks to do 1.5 ks with a bloody jackhammer,pick and crowbar then we had to cart soil in to bed the posts and strainers , the owner of the property was trying to save money by us doing it instead of getting a contractor, I went back for a visit a few years ago and his son had pulled the fence down and turned the area into a quarry for the farm , bloody excellent tracks on the farm now better than the highways we use today no potholes but a hell of a lot of traffic just maintained properly
I hear you Roger, I have had a similar experience - I blasted a heap of farm fence post holes, just in mudstone but it was a bit hard to auger. Fence went in and looked good, few weeks later the fence contractor calls up and says we have to do it all again because the customer did not like the fence line interrupting his view to the horizon while he was sitting in his pool. He got in a D9 dozer and ripped thousands of cubic meters out and then we put the fence in again!!
as a digger operator i can only imagine the relief for those blokes when you showed up an the hammers came off 😅
Loads o rock. Yet drilled piles along the boundary?
Those piles too many weeks to drill. Were they really needed???
@@demolitiondavedrillandblast That was what had me scratching my head, trying to figure out "why".
Wonder what the brick wall next door cost with all the piers holding it up. That’s for the great view of the ocean this morning, Dave.
The piers were put in to protect the neighbors drive way - took months to drill all those holes!
just a few rocks - nope...loads.. .no match for Mr D - watch me turn them into pebbles - thanks for sharing this with us stay safe and well sending regards
Glad you enjoyed it MLE.
Sweet. You even started using the new blue funnels. Now If they would get your new drill back to you.......Fixed.
Oh yeah!
Do you train other people to drill and fire the detonators? Are there many applicants for the job of "trainee explosives detonation"?
Lots of people have wanted to try out over the years... until they do a day on the drill and it breaks them.
Talk about Literally living on top a Rock!! 🧐
Oh yeah!
Dave by watching your video it did look horrible rock to drill, but what made me laugh was your little dirt dance. Keep it up mate good video thanks 👍👍👍👍😂
Yes, very tedious stuff to drill Lee.
Cool video-Bang!
Thanks for that
That video just flew by! Felt like 3 minutes!
Thanks for sharing 🇨🇦
Hi Paul. But this is probably not the Paul I knew in Guelph back in the 60’s
Glad you enjoyed it Paul, more coming soon.
Fascinating to watch you in action. You deserve every cent you earn, and more. What I don't understand is how can this be affordable for a domestic project. Surely it increases the cost so much as to make it prohibitive?
Plenty of homes in this area (mostly holiday homes) cost over 2 Million Dollars!
Wow, that must have come to some money. It makes you wonder if it is worth developing a site that needs so much preparation.
Oh yeah, very very pricey location Trevor.
I got the feeling those excavator operators needed a little encouragement to do it your way. Dirt not rock cover! Once they saw the results and got into the routine it worked out well.
I got him sorted out quick.
Now, that's the height of efficiency. A five hole shot yielded at least one pebble that you didn't even drill into. Good going, Dave. Have you used your new toy much?
Yes but this jobs was prior to the new drill.
Seems like the granite in Oz would make excellent abrasive and lapping compound - darn near hard as diamond.
Oh, it ruins windscreens very quickly if some of the dust settles on your windscreen wipers and you use the wipers without cleaning dust off first.
I guess they should have kept some soil onsite in the begining, would have saved some time
I'm sure the neighbours will be happy to have that job done a little sooner!
Most of these homes are empty most of the time, holiday homes.
Why don't you use tire mats on top of the blast holes
Hi Hans, good question. I own a truck load of blast mats that I rarely use, reason #1 - I have to take another truck load to and from the job (employ an extra person) when in nearly every case the soil is already there. #2 The soil provides a higher level of protection (provided you put enough on). #3 Blast mats might stop flyrock but they do little to manage the blast noise and it is the noise and over pressure that brings complaints (and unwanted spectators). #4 I no longer have to spend my weekends repairing blast mats. Thanks for watching.
Yes indeed that is a great deal of rocks. I enjoy watching your videos. "Let's drop some bangers" 😂❤
Glad you like them Alexander, there is a "free range" blasting video in the pipeline, stay tuned.
Good Tunes
Thanks Dan.
wow. moving heaven and earth for a view. $$$$$
Wow,that looks like a couple of hundred $k site costs 😮💨
Yes... it looks very expensive - just drilling for those piles along the side of the cut took many weeks.
,,good job, keep safe and have a great week...
Thanks, will do Bob.
Heck of a view!
Yes... and they pay for it.
Great result Dave as always thanks for sharing 🦘
Thanks Kerry.
Nice one, worth the wait to see you explode a lot of hard granite.
Thanks for dropping in Jeff.
enough rock there to make a new breakwater
There is actually a break water just down the road made out of my rock from a big housing estate development project 15 years ago. - The Developer managed to sell the whole 3500m3 of busted rock.
With a portable crusher on sit, you wouldn't need ANY fill or concrete aggregate. I used to service the tracked portable machines. Couple hours and that pile would be perfect size.
I hear you TG, would love to be able to turn what is often a waste product into a saleable product.
Looks expensive but considering where it is I’m sure money would be no issue!
Exactly David.
That sixteen-hole shot looked like you were loading them heavy. That should give the moles and gophers in the vicinity a bit of bother, if you have such creatures down under. I was hoping to see the Lady in Red on the job and watch how fast the drilling went. Maybe next time. Thanks Dave, take care and be safe. Cheers.
The lady in Red was still in India when this was done #62, thanks for watching.
Looks like a good team of excavators to work with!
Yes, these guys are good.
Pick another site? 😲🤔🙁
Views here alone cost millions!
I wonder what the cost difference was between having a whole crew with hydraulic breakers vs just having you come in and break it the right way. I'm assuming you saved them several man-hours doing it your more entertaining way...
Very nice
Thanks
Good times 😅❤🎉
Indeed, thanks for watching Tin Man
Hey dave can you put some bangers in some mash and let it go please ?
How about a pumpkin next Halloween?
Nightmare! Good results however :)
For sure!
Dave you are the antigranite. Destroyer of granite. ❤😂😂😂.
Is that like and AntiChrist?
@@demolitiondavedrillandblast You are more dangerous .
